Conclusions

  1. 1.

    Butyllithium (BL) forms 4∶1 and 4∶2 complex with trimethylamine (TMA). A 4∶4 complex is observed in isooctane solution at temperature below −70°C. With an excess of BL and at low temperature, disproportionation reactions lead to the formation of 4∶4 and 6∶1 complexes.

  2. 2.

    Butyllithium forms 4∶1 and 4∶2 complexes with triethylamine. These complexes are less stable than the corresponding BL-TMA complexes.

  3. 3.

    The mixed complexes of BL with TMA and TEA have been characterized. Butyllithium coordinates more firmly with THF than with TMA.
